Description

Technical Field

[0001] This invention relates to the field of machining technology, and more particularly to an assembly device. Background Technology

[0002] 3C electronic products are small in size but contain many internal components. When these components are installed on the inner wall of the casing, it is difficult for operators to secure them together manually. Taking buttons as an example, buttons are also subject to pressure from the user during product use. Therefore, they are more likely to fall off or loosen from the casing compared to other components. Simplifying the assembly process of components on the casing and improving the product yield rate has become a problem that needs to be solved. Summary of the Invention

[0003] In view of this, embodiments of the present invention provide an assembly device that uses a first fixing part and a second fixing part to fix the housing and the part to be assembled, and then uses the relative movement between the two to install the part to be assembled into the receiving cavity of the housing, thereby improving the product yield.

[0004] The assembly equipment described in this embodiment of the invention includes:

[0005] The first fixing part is provided with a shell fixing compartment, and one end of the shell fixing compartment has a window;

[0006] The second fixing part includes an extension rod, the axial direction of which is consistent with the extension direction of the housing fixing compartment. The extension rod has a contoured surface that is recessed from the side of the extension rod towards its center.

[0007] The driving unit is configured to drive the first fixing unit and the second fixing unit to move toward each other, and after the extension rod extends into the receiving cavity of the housing through the window to a predetermined distance, drive the contoured surface to move radially along the extension rod until the part to be assembled fits against the housing.

The relief groove is recessed from the center of the extension rod by the contoured surface and the contoured surface surrounds the relief groove. The support block is laterally protruded from the contoured surface of the extension rod and the contoured surface surrounds the support block. The relief groove and the support block are respectively adapted to the button type of the part to be assembled.

[0012] The number of adsorption holes is multiple and they are arranged on both sides of the clearance groove and the support block.

[0013] Furthermore, the assembly equipment also includes a support plate, which has clearance windows.

[0014] The second fixing part also includes:

[0015] Sealing components;

[0016] Air valve; and

[0017] A fixed block is fixedly connected to the end of the extension rod away from the first fixed part. The air passage passes through the fixed block and the extension rod. The negative pressure air source is connected to the end of the air passage located on the fixed block through the air nozzle. The sealing member seals the end of the air passage located on the extension rod.

[0018] The drive unit includes a first linear actuator, which is located inside the clearance window and connected to the support plate. The movement direction of the drive end of the first linear actuator is perpendicular to the support plate and is fixedly connected to the bottom of the fixing block.

[0019] Furthermore, the assembly equipment also includes:

[0020] Pressure sensor;

[0021] Buffer; and

[0022] The frame includes horizontal plates spaced above the fixed block. The pressure sensor and the buffer are mounted on the horizontal plates, with the sensing head of the pressure sensor and the buffer head of the buffer abutting against the top of the fixed block.

[0023] Furthermore, the first fixing part includes:

[0024] The moving base plate is configured to move linearly relative to the second fixed part;

[0025] The body, disposed on the moving base plate, has a receiving groove, the extending direction of the receiving groove being consistent with the length direction of the extending rod and having a first notch, the window and the first notch being located at opposite ends of the receiving groove; and

[0026] The first positioning element includes a first positioning boss and a first positioning block. The first positioning boss protrudes from the first positioning block and is operable to move relative to the first notch. The first positioning element mates with the receiving groove to form at least a portion of the housing fixing chamber. The housing is placed in the receiving groove. An open end of the housing receiving cavity is adapted to the first positioning boss and extends out from the first notch to abut against the first positioning block.

[0027] Furthermore, the first fixing part includes:

[0028] A linear track is disposed on the moving base plate, and the first positioning member is slidably disposed on the linear track.

[0029] The driving unit includes a first driving unit, which includes a driving plate and an elastic member. One end of the elastic member abuts against the first positioning member, and the other end abuts against the driving plate.

[0030] Furthermore, the assembly equipment also includes a support plate;

[0031] The driving unit includes a second linear actuator, which is disposed on the support plate. The driving end of the second linear actuator is fixedly connected to the moving base plate and the moving direction is parallel to the length direction of the extension rod.

[0032] Furthermore, the body has two planar sidewalls and a planar bottom wall located between the two planar sidewalls, the two planar sidewalls and the planar bottom wall surrounding to form the receiving groove;

[0033] The receiving groove also has a second notch, which is located at the end of the receiving groove away from the first notch;

[0034] The first fixing part further includes:

[0035] The second positioning component includes a second positioning boss and a second positioning block. The second positioning boss has an arc-shaped surface and a clearance surface on its side. The extension rod is located above the clearance surface. The second positioning boss protrudes from the second positioning block and is disposed opposite to the first positioning boss. The second positioning boss extends into the receiving groove through the second notch, and a positioning gap is formed between the arc-shaped surface and the flat bottom wall. The other opening end of the housing receiving cavity is adapted to pass through the positioning gap and abut against the second positioning block.

[0036] Furthermore, the first fixing part also includes:

[0037] The cover plate is movably connected to the moving base plate and has a fixed arc surface and an observation window.

[0038] The cover plate presses onto the housing, and the window is formed between the fixed arc surface and the clearance surface, wherein the fixed arc surface is adapted to the top of the housing, and the observation window corresponds to the part to be assembled.

[0039] Furthermore, the assembly equipment also includes:

[0040] The controller is communicatively connected to the negative pressure air source, the pressure sensor, and the first linear actuator. The controller is configured to stop the negative pressure air source from providing negative pressure and control the drive end of the first linear actuator away from the inner wall of the housing cavity in response to the pressure signal of the pressure sensor being greater than a first threshold.

[0041] The assembly equipment of this invention fixes the housing to a housing fixing chamber and fixes the part to be assembled to a contoured surface. Simultaneously, a driving unit drives the first fixing part and the second fixing part. Thus, through the telescopic movement of the extension rod relative to the receiving cavity, the part to be assembled can be fed into the receiving cavity for assembly with the housing. This avoids situations where the part to be assembled is difficult to insert due to the limited space of the receiving cavity. Furthermore, by driving the first fixing part and the second fixing part separately, the movement accuracy of the extension rod relative to the housing is ensured, enabling the part to be assembled to accurately align with the predetermined position of the housing.

[0076] The present invention is described below based on embodiments, but the invention is not limited to these embodiments. In the detailed description of the invention below, certain specific details are described in detail. Those skilled in the art will fully understand the invention even without these details. To avoid obscuring the essence of the invention, well-known methods, processes, flows, elements, and circuits are not described in detail.

[0077] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0078] Unless the context explicitly requires it, words such as "including" or "contains" throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, meaning "including but not limited to".

[0079] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0080] For ease of explanation, spatially related terms such as “inside,” “outside,” “below,” “below,” “lower,” “above,” “upper,” etc., are used herein to describe the relationship between one element or feature illustrated in the figure and another. It will be understood that spatially related terms may be intended to encompass different orientations of the device in use or extension other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as “below” or “below” another element or feature would then be positioned “above” that other element or feature. Thus, the exemplified term “below” can encompass both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially related descriptive terms used herein should be interpreted accordingly.

[0081] Figure 1 , Figure 2 , Figure 4 and Figure 5This is a structural schematic diagram of the assembly equipment in different embodiments. The assembly equipment in the figure includes a first fixing part 1, a second fixing part 2, a driving part 3, a support plate 4, and a frame 6. Below the first fixing part 1 and the second fixing part 2 is the chassis. The top plate of the chassis is the aforementioned support plate 4, and the chassis is used to house equipment such as power supplies.

[0082] Figure 3 This is a schematic diagram of the structure of window 12 and shell fixing compartment 11. The figure shows a portion of the shell A along its length using dashed lines.

[0083] Figure 6 This is an assembly diagram of housing A and part B to be assembled. The arrows in the diagram indicate the installation direction of part B when it is installed on housing A. Housing A provides protection for the product. The accommodating cavity A1 inside housing A is used to house components such as batteries or circuit boards. This product includes, but is not limited to, electronic cigarettes, mobile phones, or electronic watches. Taking an electronic cigarette as an example, housing A is the outer shell of the electronic cigarette device. Correspondingly, part B to be assembled is the button B1 of the electronic cigarette device and the bracket B2 on which the button B1 is located. After part B is installed with housing A, button B1 can be exposed to the outside of housing A through keyway A2. Unless otherwise specified, the following description uses part B to be assembled as button B1 fixed on bracket B2 as an example.

[0084] Figure 7 This is a schematic diagram of the second fixing part 2. The diagram shows a section cut out of the end of the insert rod 21.

[0085] In some implementations, such as Figure 1-4 As shown, the assembly equipment in this embodiment includes a first fixing part 1, a second fixing part 2, and a driving part 3. The first fixing part 1 is provided with a housing fixing chamber 11, and one end of the housing fixing chamber 11 has a window 12. The second fixing part 2 includes an extension rod 21, the axial direction of which is consistent with the extension direction of the housing fixing chamber 11. The extension rod 21 has a contoured surface 22, which is recessed from the side of the extension rod 21 toward the center of the extension rod 21. The driving part 3 is configured to drive the first fixing part 1 and the second fixing part 2 to move toward each other, and after the extension rod 21 extends into the receiving cavity A1 of the housing A through the window 12 to a predetermined distance, it drives the contoured surface 22 to move radially along the extension rod 21 until the part B to be assembled is in contact with the housing A.

[0086] In this embodiment, after the housing A is fixed by the housing fixing chamber 11, the accommodating cavity A1 can be opened to the second fixing part 2 through the window 12. Thus, when the second fixing part 2 and the first fixing part 1 approach each other, the insertion rod 21 can be inserted into the accommodating cavity A1 to facilitate the mutual assembly between the part B to be assembled and the housing A.

[0087] Figure 1 and Figure 3 The image illustrates a specific configuration where housing A is positioned within housing fixing chamber 11. Housing fixing chamber 11 surrounds most of the outer surface of housing A, with the top area of ​​the opening on one side of accommodating cavity A1 exposed to the extension rod 21. This facilitates the second fixing part 2 in mounting the part to be assembled, B, onto the top or side surface of accommodating cavity A1. Those skilled in the art can change the relative position of window 12 to the opening of accommodating cavity A1, thereby adjusting the mounting position of the part to be assembled, B, within accommodating cavity A1.

[0088] Specifically, such as Figure 5 As shown, taking the assembly part B installed on the top of the receiving cavity A1 as an example, the movement of the extension rod 214 in this embodiment includes a first axial movement and a first radial movement. During the first axial movement, the assembly part B moves from the outside of the receiving cavity A1 to the inside of the receiving cavity A1. In this state, the extension rod 214 maintains a predetermined distance from the top of the receiving cavity A1. During this process, when the button B1 moves to the position corresponding to the keyway A2, the extension rod 214 stops its horizontal movement. During the first radial movement, the button B1 moves towards the keyway A2 (e.g., ...). Figure 6 (As shown by the middle arrow), and finally the top of button B1 is exposed from the keyway A2. In this state, glue or double-sided tape can be applied in advance to the top area of ​​bracket B2, or to the inner wall of receiving cavity A1 at the position corresponding to bracket B2, so that the part B to be assembled can be stably attached to the inner wall of receiving cavity A1.

[0089] In summary, the assembly equipment of this embodiment fixes the housing A to the housing fixing chamber 11 and the part B to be assembled to the contour surface 22. Simultaneously, the drive unit 3 drives the first fixing part 1 and the second fixing part 2. Thus, through the extension and retraction of the insertion rod 21 relative to the receiving cavity A1, the part B to be assembled can be fed into the receiving cavity A1 for assembly with the housing A. This avoids the situation where the part B is difficult to insert due to the limited space of the receiving cavity A1. Furthermore, by driving the first fixing part 1 and the second fixing part 2 respectively through the drive unit 3, the movement accuracy of the insertion rod 21 relative to the housing A is ensured. This allows the part B to be assembled to accurately align with the predetermined position of the housing A.

[0090] Optionally, in this embodiment, the movement of the extension rod 21 also includes a second axial movement and a second radial movement. During the second radial movement, after the part to be assembled B and the housing A are fixed, the extension rod 21 moves away from the keyway A2, causing the part to be assembled B to disengage from the contour surface 22. Then, the extension rod 21 performs a second axial movement, during which the extension rod 21 disengages from the receiving cavity A1, so that the next part to be assembled B can be fixed on it.

[0091] Figure 8 This is a circuit diagram of the assembly equipment.

[0092] In some implementations, such as Figure 2 , Figure 5 and Figure 7-8 As shown, the second fixing part 2 also includes a negative pressure air source 23. The contoured surface 22 has an adsorption hole 221. The extension rod 21 has an air passage 211, which extends along the length of the extension rod 21 and communicates with the adsorption hole 221 and the negative pressure air source 23.

[0093] Specifically, in this embodiment, the negative pressure air source 23 is a negative pressure pump, which is used to extract air from the air passage 211 and the air nozzle 24, so that the part B to be assembled is subjected to atmospheric pressure and stably attached to the contour surface 22. Especially when the keyway A2 faces the bottom of the second fixing part 2, in this configuration, the contour surface 22 can also be set to face downwards. The negative pressure provided by this embodiment can attract the part B to be assembled onto the extension rod 21, preventing it from falling off.

[0094] In some implementations, such as Figure 2 As shown, the extension rod 21 has a clearance groove 222 and / or a support block 223. The clearance groove 222 is recessed towards the center of the extension rod 21 from the contoured surface 22 and the contoured surface 22 surrounds the clearance groove 222. The support block 223 protrudes laterally from the contoured surface 22 towards the extension rod 21 and the contoured surface 22 surrounds the support block 223. Figure 2 The cross-sectional area shown in the enlarged view on the left is the contour surface 22). The clearance groove 222 and the support block 223 are respectively adapted to the button B1 type of the part B to be assembled. Meanwhile, multiple suction holes 221 are arranged on both sides of the clearance groove 222 and the support block 223.

[0095] Specifically, the extension rod 21 is provided with an adjacent clearance groove 222 and a support block 223. The length direction of the clearance groove 222 and the support block 223 is consistent with the extension direction of the extension rod 21. Correspondingly, there are also two buttons B1 on the part B to be assembled, and the form of the two buttons B1 corresponds to the clearance groove 222 and the support block 223 respectively. In this embodiment, the bracket B2 is fixed by the suction holes 221 located on both sides of the clearance groove 222 and the support block 223, so that the two buttons B1 can be adapted to the clearance groove 222 and the support block 223. This ensures that when the part B to be assembled is assembled with the housing A, the button B1 can move radially along the extension rod 21 when it is pressed. Thus, after the button B1 is inserted into the keyway A2, while keeping the position of the extension rod 21 unchanged, the operator can press the button B1 by hand or tool to determine whether the pressing feel of the button B1 is smooth.

[0096] It should be understood that, to accommodate different functional requirements, the types of buttons (B1) on 3C electronic products also vary. Membrane buttons offer a degree of water resistance. Independent buttons can slide relative to the support (B2), thus providing a better tactile experience.

[0097] by Figure 2 Taking the enlarged view on the right as an example, the left side of the image shows an independent button, and the right side shows a membrane button. In this embodiment, the clearance groove 222 can avoid pressing the independent button, ensuring sufficient travel for the button. The support block 223 in this embodiment has a certain distance from the top of the membrane button, ensuring that the membrane button can be pressed downwards during testing. Simultaneously, it further limits the downward pressure distance of the membrane button to prevent it from denting due to excessive pressure. Furthermore, the multiple suction holes 221 located on both sides of the clearance groove 222 and the support block 223 further ensure that the part B to be assembled will not move arbitrarily during pressing.

[0098] Furthermore, the assembly equipment also includes a support plate 4, which has an opening 41 for clearance. The second fixing part 2 also includes a sealing member 26, an air nozzle 24, and a fixing block 25. The fixing block 25 is fixedly connected to the end of the extension rod 21 away from the first fixing part 1. The air passage 211 passes through both the fixing block 25 and the extension rod 21. The negative pressure air source 23 is connected to the port of the air passage 211 located on the fixing block 25 through the air nozzle 24. The sealing member 26 seals the end of the air passage 211 located on the extension rod 21. Meanwhile, the driving part 3 includes a first linear actuator 31. The first linear actuator 31 is partially located inside the clearance window 41 and connected to the support plate 4. The movement direction of the driving end of the first linear actuator 31 is perpendicular to the support plate 4 and fixedly connected to the bottom of the fixing block 25. In this embodiment, the clearance window 41 allows the extension rod 21 driven by the first linear actuator 31 to be aligned with the height of the accommodating cavity A1 in the height direction of the assembly equipment.

[0099] Specifically, in this embodiment, one end of the air nozzle 24 is connected to the fixing block 25, and the other end is connected to the negative pressure pump via an air tube (not shown in the figure). This separates the negative pressure pump from the insertion rod 21, preventing interference between the air tube and the housing A or the first fixing part 1 during the insertion of the insertion rod 21 into the accommodating cavity A1. Simultaneously, in this embodiment, the second fixing part 2 is driven to move via a first linear actuator 31. This first linear actuator 31 can be a slide cylinder.

[0100] In some implementations, such as Figure 1-2As shown, the assembly equipment also includes a pressure sensor 51, a buffer 52, and a frame 6. The frame 6 includes a horizontal plate 61, which is spaced above the fixing block 25. The pressure sensor 51 and the buffer 52 are mounted on the horizontal plate 61, and the sensing head of the pressure sensor 51 and the buffer head of the buffer 52 abut against the top of the fixing block 25.

[0101] In this embodiment, the pressure sensor 51 is used to detect the driving force of the first linear actuator 31, that is, the force exerted by the extension rod 21 on the housing A through the part B to be assembled. This prevents the driving force of the first linear actuator 31 from being too large and causing damage to the housing A.

[0102] Preferably, the buffer 52 in this embodiment is a hydraulic buffer 52. The hydraulic buffer 52 includes a hydraulic cylinder, a piston, a piston rod, a hydraulic cylinder head, a buffer spring, and sealing elements. In this embodiment, the buffer head of the buffer 52 is located at the extended end of the piston rod. During the first radial movement of the extended rod 21, the buffer head is used to mitigate the impact of the first linear actuator 31 on the housing A, thereby making the pressure sensor 51 detect pressure more accurately.

[0103] In some implementations, such as Figure 2 , Figure 4 and Figure 5 As shown, the first fixing part 1 includes a moving base plate 13, which is configured to move linearly relative to the second fixing part 2. The body 14 is disposed on the moving base plate 13 and has a receiving groove 15. The extending direction of the receiving groove 15 is consistent with the length direction of the extending rod 21 and has a first notch 151. The window 12 and the first notch 151 are located at opposite ends of the receiving groove 15. The first positioning member 16 includes a first positioning boss 161 and a first positioning block 162. The first positioning boss 161 protrudes from the first positioning block 162 and is operably movable relative to the first notch 151. The first positioning member 16 and the receiving groove 15 mate to form at least a portion of the housing fixing chamber 11. Wherein, as... Figure 4 As shown, when housing A is placed in receiving groove 15, one open end of receiving cavity A1 of housing A is adapted to the first positioning boss 161 and extends out from the first notch 151 to abut against the first positioning block 162.

[0104] In this embodiment, the first positioning boss 161 is used to position the accommodating cavity A1 radially. When the first positioning boss 161 passes through the opening end of the accommodating cavity A1, it can limit the positional accuracy of the opening end in the horizontal or vertical direction of the accommodating groove 15. At the same time, the first positioning block 162 can further ensure the positional accuracy of the housing A in the extending direction of the accommodating groove 15.

[0105] Figure 4The figure illustrates a specific form of the first positioning boss 161. The cross-section of the first positioning boss 161 in the protruding direction is approximately elongated, and the length direction of the elongated shape is perpendicular to the support plate 4. In the figure, the portion of the housing A extending from the first notch 151 has a gradually decreasing outer diameter but a constant inner diameter. Therefore, in order to position this area, this embodiment inserts the first positioning boss 161 through it to facilitate positioning of this area.

[0106] In some implementations, such as Figure 2 , Figure 4 and Figure 5 As shown, the first fixing part 1 includes a linear track 17. The linear track 17 is disposed on the moving base plate 13, and the first positioning member 16 is slidably disposed on the linear track 17. The driving part 3 includes a first driving part 32, which includes a driving plate 321 and an elastic member 322. One end of the elastic member 322 abuts against the first positioning member 16, and the other end abuts against the driving plate 321. In this embodiment, the first driving part 32 can move the first positioning boss 161 away from the receiving groove 15, so as to facilitate the placement of the housing A into the receiving groove 15. Then, the first driving part 32 drives the first positioning boss 161 to abut against one side of the housing A to limit the position of the housing A in the receiving groove 15. At the same time, the driving force of the driving plate 321 is transmitted to the housing A through the elastic member 322, which can also avoid excessive stress on the housing A and damage to the housing A.

[0107] Figure 2 The image shows a specific form of the first drive unit 32, where the elastic element 322 is a spring. The first drive unit 32 also includes a drive handle and a drive rod. The drive handle is hinged to the moving base plate 13 and the drive rod. One end of the drive rod is fixedly connected to the drive plate 321. During the swinging of the drive handle, the drive rod can be driven by the drive handle to push the drive plate 321 closer to the receiving groove 15 or pull the drive plate 321 away from the receiving groove 15. During this process, the operator can place the housing A into the receiving groove 15 with one hand and operate the drive handle with the other hand to perform the clamping operation on the housing A.

[0108] Optionally, the swing amplitude of the drive handle is limited to a certain range to avoid excessive stress on the housing A by the first positioning member 16. For example... Figure 2 As shown, the angle at which the drive handle is tilted toward the receiving groove 15 is at its maximum. In this state, the stress applied by the first positioning member 16 to the housing A can be kept within a certain range.

[0109] In some implementations, such as Figure 5As shown, the assembly equipment also includes a support plate 4. The drive unit 3 includes a second linear actuator 33, which is disposed on the support plate 4. The drive end of the second linear actuator 33 is fixedly connected to the moving base plate 13 and its moving direction is parallel to the length direction of the extension rod 21. The second linear actuator 33 can be a slide cylinder. In this embodiment, the second linear actuator 33 can move the first fixed part 1 closer to or further away from the second fixed part 2 to achieve the first axial movement.

[0110] In some implementations, such as Figure 2-4 As shown, the body 14 has two planar sidewalls 141 and a planar bottom wall 142 located between the two planar sidewalls 141, and the two planar sidewalls 141 and the planar bottom wall 142 surround to form a receiving groove 15. The receiving groove 15 also has a second notch 152, which is located at the end of the receiving groove 15 away from the first notch 151. The first fixing part 1 also includes a second positioning member 18, which includes a second positioning boss 181 and a second positioning block 184. The second positioning boss 181 is provided with an arc-shaped surface 182 and a clearance surface 183 on its side. The extension rod 21 is located above the clearance surface 183. The second positioning boss 181 protrudes from the second positioning block 184 and is arranged opposite to the first positioning boss 161. The second positioning boss 181 extends into the receiving groove 15 through the second notch 152, and a positioning gap is formed between the arc-shaped surface 182 and the flat bottom wall 142. The other open end of the receiving cavity A1 of the housing A is adapted to pass through the positioning gap and abut against the second positioning block 184.

[0111] Figure 3 The diagram illustrates the relative positional relationship between the positioning gap and housing A. When housing A abuts against the second positioning member 18, the lower half of the opening of the accommodating cavity A1 can be positioned by the second positioning boss 181, thereby stably confining housing A within the housing fixing chamber 11. This facilitates the insertion rod 21 accurately feeding the part B to be assembled into the accommodating cavity A1.

[0112] Easy to understand, such as Figure 4 As shown, the outer circumference of housing A is curved, and the curvature of the curved surface is not uniform along the length of housing A. When housing A is placed into the receiving groove 15 (the first positioning boss 161 has not yet positioned housing A), in this configuration, the planar sidewall 141 and the planar bottom wall 142 can pre-position housing A. That is, the bottom of housing A contacts the planar bottom wall 142, and the side of housing A contacts the planar sidewall 141. After the first positioning boss 161 positions housing A, the first positioning boss 161 and the second positioning boss 181 clamp housing A from both ends to achieve repositioning of housing A. Thus, the positioning accuracy of housing A in housing fixing chamber 11 is ensured, and excessive friction between receiving groove 15 and housing A is avoided.

[0113] In other embodiments, the shape of the receiving groove 15 is configured to perfectly match the outer wall of the housing A. This increases the manufacturing difficulty of the receiving groove 15 and reduces the adaptability of the assembly equipment to different types of housing A. Furthermore, the position of the housing A along the length of the receiving groove 15 changes before and after the first positioning member 16 and the second positioning member 18 apply force to the housing A. Therefore, the receiving groove 15 cannot consistently conform to the shape of the housing A before and after it is positioned by the first positioning member 16 and the second positioning member 18. Simultaneously, the bottom of the receiving groove 15 also causes considerable friction against the outer surface of the housing A during this process.

[0114] In some implementations, such as Figure 2-4 As shown, the first fixing part 1 also includes a cover plate 19. The cover plate 19 is movably connected to the moving base plate 13 and has a fixed arc surface 191 and an observation window 192. The cover plate 19 presses against the housing A, and the aforementioned window 12 is formed between the fixed arc surface 191 and the clearance surface 183, wherein the fixed arc surface 191 is adapted to the top of the housing A, and the observation window 192 corresponds to the part B to be assembled.

[0115] During the process of fitting the part B to the top of the housing A, the fixed arc surface 191 of this embodiment can press against the top of the housing A to prevent the housing A from being lifted by the extension rod 21. At the same time, the arc surface 182 can also avoid excessive pressing force on the housing A, causing deformation of the housing A. The observation window 192 can be used to determine whether the current button B1 is in the corresponding position with the keyway A2, and it also allows the operator to press down the button B1 through the observation window 192 to test the fit between the button B1 and the keyway A2.

[0116] In some implementations, such as Figure 1-8 As shown, the assembly equipment also includes a controller 7. The controller 7 is communicatively connected to the negative pressure air source 23, the pressure sensor 51, and the first linear actuator 31. The controller 7 is configured to stop the negative pressure air source 23 from providing negative pressure and control the drive end of the first linear actuator 31 away from the inner wall of the accommodating cavity A1 of the housing A in response to the pressure signal of the pressure sensor 51 being greater than a first threshold.

[0117] Specifically, the controller 7 in this embodiment can improve the automation level of the assembly equipment. When the first linear actuator 31 applies sufficient pressure, the controller 7 controls the negative pressure air source 23 to stop providing negative pressure, ensuring that the part to be assembled B detaches from the contour surface 22 as the extension rod 21 moves away from the inner wall of the accommodating cavity A1. This achieves the assembly of the part to be assembled B with the housing A.

[0118] The assembly equipment in the above embodiments can be operated in the following manner. In some embodiments, such as Figure 1-8As shown, firstly, double-sided tape is applied near the keyway A2 on the inner wall of housing A, and housing A is placed into the receiving groove 15. In this configuration, it is necessary to distinguish the shapes of the two open ends of the receiving cavity A1 so that one open end is fitted onto the second positioning boss 181. In this state, housing A in the receiving groove 15 will exhibit a slight tilt.

[0119] Next, place the part B to be assembled on the contour surface 22 and start the negative pressure air source 23 to stably adsorb the part B to be assembled onto the extension rod 21.

[0120] Next, the drive handle is operated to abut the first positioning member 16 against the other opening end of the accommodating cavity A1. In this state, the position of the housing A on the first fixing part 1 can be stably restricted within the housing fixing chamber 11.

[0121] Furthermore, the controller 7 drives the second linear actuator 33, causing the first fixing part 1 to move the housing A toward the extension rod 21 until the button B1 aligns with the keyway A2, i.e., the first axial movement. In this state, the alignment of the two can be determined through the observation window 192.

[0122] Furthermore, the controller 7 drives the first linear actuator 31, causing the bracket B2 to adhere to the position where the double-sided adhesive is located on the housing A, i.e., the first radial movement. In this configuration, the button B1 protrudes from the keyway A2. The operator can use a tool to press the button B1 exposed in the observation window 192 to test whether its movement meets the requirements.

[0123] Specifically, the driving force of the first linear actuator 31 is ensured to be within a certain range, and the duration of the driving force is also within a certain range (e.g., 4 seconds or 5 seconds). This ensures that the double-sided adhesive can firmly bond the part B to be assembled and the housing A.

[0124] Finally, the negative pressure supply from the negative pressure air source 23 is stopped by the controller 7. Then, the first linear actuator 31 is driven, causing the extension rod 21 to move away from the keyway A2, i.e., the second radial movement. Then, the second linear actuator 33 is driven, causing the extension rod 21 to be pulled out of the receiving cavity A1 (i.e., the second axial movement) and the cover plate 19 to open. The first positioning member 16 is driven away from the receiving groove 15, and the assembled product is removed.

[0125] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of protection of the present invention.
